　　超声波清洗机预处理

　　Ultrasonic cleaning machine pretreatment

　　清洗之前宜用竹刀先将零部件表面的污垢（如防尘罩外表面会有很多尘土、气缸体类的零件在其外壳曲线变化处会积留很多厚且易除的油泥）简单清洁一下，以便延长清洗液使用寿命。

　　Before cleaning, it is advisable to use a bamboo knife to clean the dirt on the surface of the components (such as a lot of dust on the outer surface of the dust cover, and a lot of thick and easily removable oil sludge will accumulate at the curve changes of the cylinder body), in order to extend the service life of the cleaning solution.

　　超声波能够进行精密清洗，但其对泥类的污物处理能力较弱，故预处理中，应尽量将黄泥或稀泥类的污物去除。

　　Ultrasound can perform precision cleaning, but its ability to treat mud like dirt is weak. Therefore, in pre-treatment, yellow mud or thin mud like dirt should be removed as much as possible.

　　工作原理

　　working principle

　　通过换能器，将功率超声频源的声能转换成机械振动，通过清洗槽壁将超声波辐射到槽子中的清洗液。由于受到超声波的辐射，槽内液体中的微气泡能够在声波的作用下快速变大破裂，破裂时产生的高强度剪切力作用于各类样品上，从而达到清洗、提取、乳化、加速溶解、粉碎、分散等作用。

　　By using a transducer, the sound energy of the power ultrasonic frequency source is converted into mechanical vibration, and the ultrasonic waves are radiated into the cleaning solution in the tank through the cleaning tank wall. Due to the radiation of ultrasound, microbubbles in the liquid in the tank can quickly grow and rupture under the action of sound waves. The high-strength shear force generated during rupture acts on various samples, achieving cleaning, extraction, emulsification, accelerated dissolution, crushing, dispersion, and other functions.

　　超声波清洗机功率如何选择？

　　How to choose the power of an ultrasonic cleaning machine?

　　超声清洗效果不一定与（功率×清洗时间）成正比，有时用小功率，花费很长时间也没有污垢。而如果功率达到一定数值，有时很快便将污垢去除。若选择功率太大，空化强度将大大增加，清洗效果是提高了，但这时使较精密的零件也产生蚀点，得不偿失，而且清洗缸底部振动板处空化严重，水点腐蚀也增大，在采用三氯乙烯等有机溶剂时，基本上没有问题，但采用水或水溶性清洗液时，易于受到水点腐蚀，如果振动板表面已受到伤痕，强功率下水底产生空化腐蚀更严重，因此要按实际使用情况选择超声功率。

　　The effect of ultrasonic cleaning may not be directly proportional to (power x cleaning time), and sometimes using low power may take a long time without removing dirt. If the power reaches a certain value, sometimes the dirt is quickly removed. If the selected power is too high, the cavitation intensity will greatly increase, and the cleaning effect will be improved. However, at this time, more precise parts will also produce corrosion points, which is not worth the loss. Moreover, the vibration plate at the bottom of the cleaning cylinder will have severe cavitation and increased water point corrosion. When using organic solvents such as trichloroethylene, there is basically no problem. However, when using water or water-soluble cleaning liquids, they are prone to water point corrosion. If the surface of the vibration plate has been damaged, the cavitation corrosion at the bottom of the water will be more severe under high power. Therefore, ultrasonic power should be selected according to actual usage conditions.
